Hi

In order to automatically reconnect after a disconnection, either the iOS application will be able to scan for the specific device in the background, or the peripheral will have to advertise as one of the natively supported services that are able to connect to an iPhone by default (The HID service and Apple Notification Center Service come to mind). iOS is rather "strict" as to how much an iPhone is allowed to scan for (in order to save power), so this might take a while. This background scanning has to be implemented in the iOS app though.

Best regards,

Simon
